LENS GUIDE
Understand what the lens actually does.
Polarization, UV filtering, tint, material, and photochromic behavior are separate features. This hub keeps the terminology simple so you can compare products without relying on vague “premium lens” language.
Polarized vs. non-polarized
What polarization changes, where glare reduction helps most, and why it is different from UV protection.
UV400 explained
What the label is intended to mean and why visible lens darkness does not prove ultraviolet filtering.
Lens colors
Compare gray, brown, green, yellow, and mirrored tints by brightness, contrast, and color perception.
TAC lenses
Why TAC appears in many polarized sunglasses and which lens claims still need to be verified separately.
Browse by verified lens feature.
Use our Polarized and Photochromic collections when you want a specific lens function rather than only a frame shape.
